A Stage 3 kit that worked GREAT in 2001!!!! And STILL works. This properly designed Intake System adds more low-end / midrange and more top-end power. It doesn't loose lowend and midrange - like the Jersey jet kit, "4th gear wack", guy. Easy to install and tune - no slide or carb body drilling.

Adds more low-end / midrange and if the proper main jet is selected, more top-end power. Banished the 4k Buzz in December 2000!! Easy to install and tune - no slide or carb body drilling like other kits that often end up with poor fuel mileage and no place to turn to to fix. 1. Bikes with Factory's FZ1 kits have never had fuel leakage problems, like some others, as we have always stressed the importance of setting fuel levels (float heights) to proper tuning and mechanical specifications from day one. No magic - just good engineering from the start. 2.Factory kits smooth out the 4000 rpm buzz - the larger pilot, in conjunction with the proper needle base diameter, simply erases the buzz - In fact - we never even thought of the FZ1 as a particularly "buzzy" bike, as we never had a buzz after we tuned the bike - The EC997 dynes will actually display "engine smoothness" in realtime. 3. Factory Pro's Y69 kit specifies staggered main jets - Why? Because the EC997 Low Inertia dyne systems CAN see the power difference in only 1 jet size change on only 2 carbs - and common, dealership level dynes just can't function at that detail level - You'd be surprised at who uses a dealership level dyno to "design" products...... 4. It took some time to develop the kit - but we didn't have to make 35 different needles or anything like that - Proper dyne test equipment allows pertinent information that guides the kit designer in the proper direction - without flailing and jetting by "luck" and then bragging about how hard it was - 5. Conserving fuel mileage is a normal Factory Pro goal - The Y69 Series kit will deliver the best performance while retaining the best mileage possible when properly tuned. 6. Even though great results are obtained by simply dropping in the kit as per suggested settings, Factory Pro's Y69 Series kit contains several different main jet sizes to allow a discriminating tuner/owner to obtain the BEST performance - regardless of the temperature, humidity, elevation, local fuel type - It ridiculous to assume that every FZ1 will take the same size main jet. 7. For best performance, the RTR-YAM-68-04 Ignition Advance will absolutely improve part throttle power (snap and wheelie) and has improved full throttle power on every FZ1 that's been properly tuned. 8. Part throttle power? It's improved - as is Throttle
Linearity - Cutting springs and opening up slide damping holes decreases
the "control" that the rider has when "riding the twisties" esp. when
riding "2-up". |

Adding the BMC Street filter will add ~1hp at high rpm when properly jetted (~1mj increase) and will "clean up" low-end richness when fully warmed upon stock carbureted bike otherwise.
The picture shows 2 FZ1 filters for detail - The bike uses only one. |

Just installed the Factory Pro Carb Kit - 1st impressions
Well, for the impressions now... I took the bike for a short ride and it worked very well "out of the box", even before the carb sync. It seems a tad weak below 2000rpm (big deal..) but really takes off from 3500 rpm (i.e. the front feels real light) with a beautiful linear feel.
The engine is not rough anymore, almost silky.
I'll take it for another spin tonight when traffic is lighter and will let you know should anything else comes to my mind. Note that the oem bike, despite its 20K miles, was working well before the install and had been tuned up recently.
But nothing compared to now.
Bottom line: when faced with the task of installing the kit yesterday evening, and
wondering whether it would work well once put back together, I had second thoughts.
But now I wonder why I did not buy this kit earlier. Great investment, and cheaper
than a new bike.
Now, for those without a carb kit: what are you waiting for ?
Ciao,
Pierre
